Here's a tutorial on how to install Euclidean Android Nougat custom ROM on Google Nexus 5.

Since Google has disbanded the official software update service to the 2015 series Nexus 5, it will not be getting the latest Nougat firmware.

That said, Nexus 5 owners would still be able to enjoy Google's new candy-flavoured OS, thanks to the Euclidean custom ROM. It is developed by the XDA Developer Forum members and comes with all the Nougat features and also the new short-cuts, exclusive themes, wallpapers, performance tweaks and other value-added features to enhance user-experience.

This new Android 7.0 Nougat Euclidean custom ROM has to be installed on Google Nexus 5 (aka Hammerhead) LTE only model, if tried on other devices, it might get bricked [to check your device model: Go to Settings >> About phone >> model number].

Make sure the device is rooted before going ahead with custom ROM installation.

AOSP ROM has to be installed through TWRP only

Installation of custom ROM requires clearing the memory in the tablet, so make sure to back all the data by installing TWRP in the smartphone.

Make sure USB driver is installed in the PC or else your device (Google Nexus 5) will not be recognised by the computer.

Make sure your device has more than 80% battery, or else there is a chance of the tablet getting temporarily bricked if the installation process is interrupted midway.

Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void; the company will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
